cannot understand the if command

Question

I'm trying to write a program, which shows a custom message in the console when I type load. But I can't seem to get it to work. :/

#include "stdafx.h"
#include "iostream"
#include "string"

using namespace std;

int main()
{
    int commands();
    string text;
    cout << "Write your registered e-mail to continue...\n";
    cin >> text;

    string input;
    cout << "\n";
    cout << "Welcome " << text << endl;
    cout << "\n";
    cout << "www.steamcommunity.com/id/thetraderdazz> ";
    cin >> input;
    if (input = load);
    cout << "loading...";

    system("pause");

    return 0;
}

It also gives me the following error:

identifier "load" is undefined.

You seem to have quite a few misunderstandings about C++. You should take a step back and systematically learn the language from a good book. — Baum mit Augen, Aug 26 '17 at 14:27
Agree with comment above. Here's some help with your particular problem https://stackoverflow.com/questions/6222583/how-to-compare-strings — ivo, Aug 26 '17 at 14:28
I agree with all the comments above, but first, you should be using the strcmp function instead of `=` (which does assignment, I think you meant `==`) and you have to make `load` a string, so: `"load"`. — Alexis Dumas, Aug 26 '17 at 16:07

if (input = load);

There are three mistakes with this line. The first is that you used the assignment operator = instead of comparison operator ==. The former assigns, the latter compares.

The second mistake is that you placed a semicolon after the parenthesis, indicating an empty body. Your compiler should have given you a warning about this.

Finally, there is no variable load. You mean to compare to string literal "load".

Fix to

if (input == "load")
    cout << "loading...\n";

You probably intended the following

if (input == "load") {
 cout << "loading...";
}
